The effects of overinflation of the lung in obstructive lung disease on the function of chest wall (rib cage, diaphragm) were studied. Concerning the function of the rib cage, the lateral motion of the lower lateral rib cage was evaluated using several experimental models. The results showed that the lower lateral rib cage was moved by many factors, including the force of the diaphragm, rib cage, compliance of abdominal wall, zone of apposition and angle of the diaphragm at the part of its insertion into the rib cage with respect to the transverse section of the trunk. The inward motion of the lower lateral rib cage due to overinflation of the lung occurred by participation of these factors. Concerning the function of the diaphragm, the diaphragm at high lung volume in healthy subjects and patients with pulmonary emphysema was evaluated by the three-dimensional stereoscopic method. The radius of the portion of the dome in the diaphragm decreased at higher lung volume, and changes in lung volume at that lung volume were caused by changes in the shape in the posterior of the diaphragm.

UI	MeSH Term	Description	Entries
D008173	Lung Diseases, Obstructive	Any disorder marked by obstruction of conducting airways of the lung. AIRWAY OBSTRUCTION may be acute, chronic, intermittent, or persistent.	Obstructive Lung Diseases,Obstructive Pulmonary Diseases,Lung Disease, Obstructive,Obstructive Lung Disease,Obstructive Pulmonary Disease,Pulmonary Disease, Obstructive,Pulmonary Diseases, Obstructive
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
